Risks of Trading Structured Warrants
All the risks of trading structured warrants — time decay, leverage losses, issuer risk, liquidity risk, and mandatory call risk for CBBCs — explained with practical examples.

Time decay risk
Every structured warrant loses time value each day as it approaches expiry — this is time decay (theta). The erosion is small in the early months but accelerates sharply in the final 30–60 days. A trader who buys a warrant and holds it without the underlying moving sufficiently will watch the position lose value daily, even if their directional view turns out to be correct eventually but too late.
Practical impact: a warrant bought at RM0.20 with 30 days to expiry might lose RM0.01–0.02 per day to time decay alone, depending on its moneyness and implied volatility. Over two weeks of flat underlying price action, that's 5–10% of the position erased by the clock alone. This is why time decay is often called the hidden cost of leverage.
Leverage risk: amplified losses
Leverage is the defining feature of structured warrants — and its defining risk. A warrant with 5× effective gearing will lose roughly 5% for every 1% adverse move in the underlying. While the maximum loss is always capped at the premium paid (you can never owe more than you invested), losing that full premium is common. A modest 3–5% move against the position, combined with time decay, can wipe out a large portion of the warrant's value in a matter of days.
This is fundamentally different from holding the underlying stock, where a 5% decline is uncomfortable but recoverable. A warrant can go from breakeven to near-worthless on the same 5% move if it's out-of-the-money and near expiry. Leverage amplifies gains and losses equally — never treat it as a one-sided benefit.
Issuer (counterparty) risk
A structured warrant's payout depends on the issuing financial institution honoring its obligation at maturity. Unlike exchange-cleared options (where a clearinghouse guarantees the trade), a warrant holder bears the credit risk of the specific issuer. In practice, issuers active on Bursa Malaysia and HKEX (Macquarie, RHB, Kenanga, CIMB, Maybank IB, and others) are regulated and well-capitalized institutions, and issuer default on a structured warrant has not occurred in these markets — but the theoretical risk exists and distinguishes warrants from cleared options.
Liquidity and spread risk
Not all warrants trade with tight bid-ask spreads or high volume. Illiquid warrants — those with few market participants or sporadic issuer quoting — can have wide spreads that eat into returns. Buying at the ask and selling at the bid on a warrant with a 10% spread means starting the trade 10% in the hole before the underlying moves at all. Always check the bid-ask spread and daily volume before entering a position, and prefer warrants where the issuer actively quotes tight, continuous prices.
Mandatory call risk (CBBCs only)
CBBCs carry an additional risk that standard structured warrants do not: mandatory call. If the underlying touches the CBBC's call level at any point before expiry — even briefly, even on an intraday wick — the contract is immediately terminated and trading stops. The holder receives either zero residual value (Category N) or a partial residual (Category R), but in either case the position is forcibly closed and cannot recover, regardless of where the underlying moves afterward. This risk is distinct from time decay or leverage — it's a binary event that can end the trade in seconds during volatile markets.
How to manage warrant risks
Position sizing is the most important risk-management tool for warrant trading — never allocate more capital to a warrant position than you can afford to lose entirely. Beyond sizing, choose warrants with sufficient time to expiry (to reduce time-decay pressure), compare bid-ask spreads across issuers (to reduce execution cost), and monitor your position actively rather than buying and holding passively. Structured warrants are active trading instruments, not buy-and-forget investments.
FAQ
What is the maximum I can lose on a structured warrant?
The maximum loss on a long warrant position is capped at the premium paid — you can never lose more than your initial investment. But losing the full premium is common if the underlying doesn't move as expected before expiry.
Are structured warrants riskier than stocks?
Yes — due to leverage and time decay. A 5% adverse move in the underlying can cause a 25%+ loss in a warrant with 5× effective gearing, and the position loses value every day regardless of direction due to time decay. The maximum loss is capped at the premium, but reaching that cap is more common than with stocks.
What happens if a warrant issuer goes bankrupt?
The warrant's payout depends on the issuer honoring its obligation, so issuer bankruptcy could theoretically result in total loss. In practice, issuers on Bursa Malaysia and HKEX are regulated, well-capitalized financial institutions, and no issuer default on a structured warrant has occurred in these markets.
